SPECIFICATION forming part of Letters Patent No. 771,181, dated September 27, 1904.

I Application filed November 2, 1903. Serial No. 179,498. (No model.)

To LZZ whom, t may concern:

Be it known that I, EVERETT R. SHETTLE, a citizen of the United States, residing at Spirit Lake, in the county of Dickinson and State of Iowa, have invented certain new and useful Improvements in Portable Grain- Dumps, of which the following is a specication.

The objects of my invention are to provide adevice of this class of simple, durable, and inexpensive construction and of light Weight, so that it may be readily and easily transported.

A further object is to provide a device of this class which may be placed fiat upon the ground surface and which does not require the use of inclined approaches.

A further object isto provide a device of this class in which the use of an engine is dispensed with and no power is necessary except that furnished by the teams of the wagons being dumped and also that furnished by a crank to be turned by the operator.

A further object is to provide a machine of this class in which the operation of dumping the wagon and of discharging the contents thereof at an elevated point may be accomplished quickly and the apparatus prepared to receive a second load as soon as the first is discharged.

My invention consists in certain details in the construction, arrangement, and combination of the various parts of the device whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which- Figure 1 shows a perspective view of the complete apparatus with the elevator-box in position for discharging its contents and also a wagon in position in the device. Fig. 2 shows a side elevation of the complete device with the elevator-box in its lowered position anda wagonin position with its rear end over the elevator-box.y The dotted lines in said figure indicate the position of the wagon and the accompanying parts with its front end elevated and its rear end over the rear of the elevator-box. Fig. 3 shows a front end elevation of the complete device with the elevator-box in its loweredposition. The dotted lines in said figure indicate the position of the elevator-box when4 discharging. Fig. 4 shows an enlarged transverse sectional view of the elevator-box and a tripping device for supporting the hinged side thereof. The dotted lines in said figure indicate the position of the parts when the hinged side is opened as required to discharge. Fig.` 5 shows an enlarged detailed perspective view of one of the wagon-platform -supporting tracks. Fig. 6 shows aplan view illustrating the mechanism for applying the power to raise the elevatorbox and to lock it in its elevated position.

Referring to the accompanying drawings, I have used the reference-numeral 10 to indicate the sills of the device. These sills are preferably rounded at their ends to form runners by which the device may be transported. Erected on top of the rear ends of the sills is a frame 1l, and erected on top of the front of the sills is a frame 12. Said sills are spaced apart far enough and said frames are of such shape that a team of draft-animals attached to a loaded wagon may readily pass between the sills and under the frame.

The elevator-box is composed of a solid bottom 13, ends 14, and stationary side 15, attached to the bottom and ends, and a hinged side 16. This hinged side is connected with the elevator-box by means of the hinges 17, attached to the cross-pieces 18 beneath the bottom 13 and also attached to the inner face of the hinged side 16. By this arrangement of parts the hinged side will stand on a lower plane when open than the top of the bottom 13, as shown in Fig. 4. This elevator-box is supported by means of four ropes. The first one (indicated by the numeral 19) is attached to an evener 20, passed under a pulley 21 at the base of the frame 11, then over a pulley 22 at the top of the frame 11, and on its end is a hook 23, detachably connected with the eyebolt 24, secured to one of the cross-pieces 18 near the front of the elevator-box. The

second rope, 25, is attached to the evener 20, passed under the pulley 26 near the base of the frame 11, then. over the pulley 27 at the top of the frame 11, then across the top of the frame 11 and around the pulley 28, then over the pulley 29, and its other end is provided 100 with a hook 30, detachably connected with the short loop 31, which is secured to the bottom 13 at a point inside of the hinged side piece 16 and extends to a point above the box.

These two ropes 19 and 25 support the front end of the elevator-box. The rear end of the elevator-box is supported by means of a rope 32. One end of this rope is attached to the evener 20, and the rope passes under pulley 33 at the rear of the base of the frame 11, then upwardly and over the pulley 34 at the top of the frame 11, and the other end of the rope is permanently secured to the elevatorbox near the rear end thereof. The other rope, 35, is attached to the evener 20, passed under pulley 36, then over pulley 37, then around pulley 36, then over pulley 39, and its end is attached to the elevator-box in the same way as the rope 25. By the arrangement just described a pull upon the evener 2O will raise the elevator-box to the top of the frame 11. The two ropes 19 and 35 -are attachedl to one end of the evener 20, and thc other two ropes, 25 and 32, are attached to the other end of said evener, and .obviously when a wagon or a pair of draft-animals is attached to the central portion of said evener and advanced and the further movement of one pair of the ropes is stop pcd then a further advance of the evener will obviously move the other pair of ropes a slight distance.

I have provided means by which an unloaded wagon passing from the device may be utilized in raising the elevator-box, as follows: The numeral indicates a pulley connected by a chain 41 to the evener 20, and the pulleyy 42 is attached to the stationary post 43. A rope or cable 44 is provided with a hook 45 `on one end and is then passed around the pulley 40 and then around the pulley 42, and its other end is attached to the eye 46 of the pulley 40. This hook 45 is attached to the rear of a wagon passingI from the device, and as the wagon advances the pulley 40 is moved toward the pulley 42, and the elevator-box is thereby raised. When the wagon is stopped, the automatic clutch, composed ofthe stationary jaw 47 and the movable jaw 48, grips the rope 44 and holds the box in its elevated position. WVhen it is desired to lower the box, the movable jaw 48 is released from the rope, and the elevator-box will then be lowered by gravity.

l. have provided means whereby the hinged side 16 of the elevator-box is normally locked and is automatically released when the clevator-box reaches its upper limit of movement, as follows: The numeral 49 indicates a loop fixed to the inner face of the side 16 and pivotally connected to a strap 50 on a bar 51. This bar is provided with the longitudinal slot 52, with notches 53 at the upper side of the slot. The pin 54 passes through the slot and is fixed to the adjacent end 14 of the elevator-box. When the side 16 is closed, the

bar 51 is in position with the pin 54 resting in the outer one of the notches 53, as shown in solid lines in Fig. 4, and the weight of the bar 51 securely holds it in this position. The numeral 55 indicates a lever pivoted at 56 to the end 14. Said lever projects upwardly and outwardly from the hinged side of the box. The numeral 57 indicates a second lever pivoted at 58 to the end 14 below the bar 51, and a link 59 connects these levers, said parts being so arranged that when the outer end of the lever 55 is moved downwardly the inner end of the lever 57 moves upwardly and carries with it the bar 5l, thus throwing the bar to position with the pin 54 in the slot 52 and permitting the hinged side 16 to drop t0 its open position, when the pin 54 will enter the opposite end of the slot 52. In this connection it is to be understood that each end of the elevator-box is provided with a similar device, and a cross-piece 59a is provided on the frame 11 in a position where the levers 55 will strike it when the elevator-box approaches the upper end of its movement.

As shown in Fig. 3 of the drawings, the hopper 60 is secured to the side of the frame 11 in position to receive the discharge from the elevator-box, and a spout 61 is connected with this hop per, through which the contents of the hopper will discharge. As soon as the elevator-box is lowered the side 16 is moved inwardly on its hinges until the pin 54 enters the central notch 53 of the bar 51, and thus locks the side 16 in its partially-closed position. 1t is fully closed by hand when box is lowered.

I have provided means for elevating the forward end of the wagon, so that its contents may be discharged into the elevator-box, as follows: On the front end of the frame 11 are two brackets 62, and resting upon these brackets are the beams 63. These beams are identical in construction, and but one will be hereinafter described. In the top of the beam is a groove 64, and at the rear end of the beam are the uprights 65. Mounted on top of the beam is a rectangular frame 66, in which a number of rollers 67 are mounted, the axles 68 of said rollers being rotatably mounted in the sides of the frame 66 and the body portion of said rollers entering the groove 64. The frame containing these rollers is designed to move throughout the entire length of the said beam. Mounted on top of the rollers is a flat strip 69, with downwardly-projecting edges 70. The strip 69 rests on top of the rollers 67, and the sides 7 0 project downwardly over the ends of the rollers to a point near the frame 66. The numeral 71 indicates a cross-piece fixed to both of the parts 69. By this arrangement of parts it is obvious that the cross-piece 71 may move with a minimum of friction throughout the length of the beams 63. Fixed to the cross-piece 71 are two cables 72, supporting a platform, which is constructed as IOO i IIO `and to rest upon the sills 73.

follows: The base of the platform is composed of two transverse sills 73. These sills are connected byrboards 74 at their ends and also by boards 75 at their central portions, thus leaving' openings between the sills 73, said openings 'being spaced apart at the proper distance to admit the front Wheels of the wagon to pass through between the vboards 74 and 75 At the ends of the platform thus formed are the inclined approaches 76. I have provided means for raising and lowering this platform, as follows: The numeral 77 indicates a shaft mounted in the frame 12. The numeral 78 indicates ropes or cables fixed to and wound upon the shaft 77, passed over the pulleys 79, and attached to the front ends of the beam 63. For rotating the shaft 77 as required to elevate and lower the beam 63 I have provided a large drum 80, fixed 'to the shaft 77 and having a rope or cable 81 fixed to and wound upon the drum lat one end, with its other end fixed to a'nd wound upon the shaft 82, which shaft is provided with a crank 83, by which it may be manually rotated. K

In practical use and assuming the device to be inthe position shown in Fig. l and assuming, further, that the wagon therein illustrated lhas been driven into the position'shown by passing under the frame 11 and stopping with 'its front wheels in the platform,I as shown,

the operator first permits the elevator-box to descend and rest upon the ground in the rear of thewvagon. This is done'by releasing the clutch composed ofthe parts 47 and 48. The hinged side of the elevator-box is then closed. The front end of the wagon is then elevated without detaching the draft-animals from the wagon by a manipulation of the crank 83. When the beams 63 are in a substantially horizontal position, then the front end of the Wagon is held in this position, and the draft-animals attached thereto'are backed until the rear end of the wagon overlaps the front end of the elevator-box. The wagon will be easily backed, because a portion of its weight rests upon the cross-piece 7l, which in turn is supported on the rollers. Then the end-gate of the wagon is removed and the load is discharged into the elevator-box. While the load is being discharged the wagon is backed, so that the load will be distributed evenly throughout the length of the elevator-box. The front end of the beams 63 is then lowered and the wagon moved forwardly beyond the elevator-box, and when the platform rests upon the ground the wagon may be advanced beyond the device. Then the hook 45 is attached to the rear end of the wagon, and when the wagon is further advanced the elevator-box will be raised, by means of its supporting-ropes, until the levers 55 strike upon the cross-piece 59, This will stop further elevation of one side of the elevator-box and at the same time will release the hinged side. The other side of the box, however, will continue to rise on account of the action of the evener 20, and when further advance of one end of said evener is stopped a further pull at the center` of the evener will cause vthe other end of the evener to advance a slight distance or until the bottom of the elevator-box is at such an incline that its contents will discharge into the hopper 60. As soon as the elevator-box has reached its upper limit of movement the hook 45 is detached from the wagon and the device is ready to receive another wagon. The ropes 19 and 25 are detachably connected with the forward end of the elevator-box, so that when the elevator-box is Vresting on the ground these ropes may be removed in order that the wagon may be backed over the elevator-box. V

Then when the wagon is advanced the ropes are again attached.
